NAME

6       nghttpd - HTTP/2 server
7

SYNOPSIS

9       nghttpd [OPTION]... <PORT> [<PRIVATE_KEY> <CERT>]
10

DESCRIPTION

12       HTTP/2 server
13
14       <PORT> Specify listening port number.
15
16       <PRIVATE_KEY>
17              Set    path   to   server's  private   key.    Required   unless
18              --no-tls is specified.
19
20       <CERT> Set   path   to   server's   certificate.     Required    unless
21              --no-tls is specified.
22

OPTIONS

24       -a, --address=<ADDR>
25              The address to bind to.  If not specified the default IP address
26              determined by getaddrinfo is used.
27
28       -D, --daemon
29              Run in a background.  If -D is used, the current working  direc‐
30              tory  is  changed to '/'.  Therefore  if this option is used, -d
31              option must be specified.
32
33       -V, --verify-client
34              The server  sends a client certificate  request.  If the  client
35              did   not  return   a certificate, the  handshake is terminated.
36              Currently,  this  option just  requests   a  client  certificate
37              and does not verify it.
38
39       -d, --htdocs=<PATH>
40              Specify  document  root.   If  this option is not specified, the
41              document root is the current working directory.
42
43       -v, --verbose
44              Print debug information   such  as  reception/  transmission  of
45              frames and name/value pairs.
46
47       --no-tls
48              Disable SSL/TLS.
49
50       -c, --header-table-size=<SIZE>
51              Specify decoder header table size.
52
53       --encoder-header-table-size=<SIZE>
54              Specify  encoder header table size.  The decoder (client) speci‐
55              fies  the maximum  dynamic table  size it   accepts.   Then  the
56              negotiated  dynamic  table  size  is  the minimum of this option
57              value and the value which client specified.
58
59       --color
60              Force colored log output.
61
62       -p, --push=<PATH>=<PUSH_PATH,...>
63              Push  resources <PUSH_PATH>s  when <PATH>  is  requested.   This
64              option   can  be used repeatedly  to specify multiple push  con‐
65              figurations.    <PATH>  and    <PUSH_PATH>s   are  relative   to
66              document  root.   See   --htdocs  option.  Example: -p/=/foo.png
67              -p/doc=/bar.css
68
69       -b, --padding=<N>
70              Add at  most <N>  bytes to a  frame payload  as padding.   Spec‐
71              ify 0 to disable padding.
72
73       -m, --max-concurrent-streams=<N>
74              Set  the maximum number of  the concurrent streams in one HTTP/2
75              session.
76
77              Default: 100
78
79       -n, --workers=<N>
80              Set the number of worker threads.
81
82              Default: 1
83
84       -e, --error-gzip
85              Make error response gzipped.
86
87       -w, --window-bits=<N>
88              Sets the stream level initial window size to 2**<N>-1.
89
90       -W, --connection-window-bits=<N>
91              Sets   the   connection   level    initial   window   size    to
92              2**<N>-1.
93
94       --dh-param-file=<PATH>
95              Path  to file that contains  DH parameters in PEM format.  With‐
96              out  this   option,  DHE   cipher  suites   are  not available.
97
98       --early-response
99              Start sending response when request HEADERS is received,  rather
100              than complete request is received.
101
102       --trailer=<HEADER>
103              Add a trailer  header to a response.   <HEADER> must not include
104              pseudo header field  (header field name starting with ':').  The
105              trailer  is  sent  only  if  a response has body part.  Example:
106              --trailer 'foo: bar'.
107
108       --hexdump
109              Display  the   incoming  traffic  in    hexadecimal   (Canonical
110              hex+ASCII  display).   If  SSL/TLS   is used, decrypted data are
111              used.
112
113       --echo-upload
114              Send back uploaded content if method is POST or PUT.
115
116       --mime-types-file=<PATH>
117              Path  to file  that contains  MIME media  types and  the  exten‐
118              sions that represent them.
119
120              Default: /etc/mime.types
121
122       --no-content-length
123              Don't send content-length header field.
124
125       --ktls Enable ktls.
126
127       --no-rfc7540-pri
128              Disable RFC7540 priorities.
129
130       --version
131              Display version information and exit.
132
133       -h, --help
134              Display this help and exit.
135
136       The <SIZE> argument is an integer and an optional unit (e.g., 10K is 10
137       * 1024).  Units are K, M and G (powers of 1024).
